php - 无法连接：无法通过套接字'/var/lib/mysql/mysql.sock'连接到本地MySQL服务器（2）

Question

当我通过 php 脚本连接我的数据库时，它显示

Could not connect: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

用户名和密码是正确的。

的东西my.cnf

[client]
#password       = your_password
port            = 3306
socket          = /data/mysql/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port            = 3306
socket          = /data/mysql/mysql.sock
skip-external-locking

ps：我把它改成socket = /var/lib/mysql/mysql.sock php脚本仍然说“/var/lib/mysql/mysql.sock”？。然后运行

  mysqladmin -u root -p status

表明

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!




service mysqld restart


mysqld: unrecognized service

Answer 1

问：您的 my.conf 是否仍然显示“/var/lib/mysql/mysql.sock”？

问：目录“/var/lib/mysql”是否存在？

问：你的 mysql 用户（或者更好的 mysql 组）是否有 writer 权限？

如果是这样，请尝试重新启动mysql，看看会发生什么。

要尝试的另一件事是创建一个 mysql.sock 并显式授予它权限：

cd /var/lib
mkdir mysql
touch mysql/mysql.sock
chown -R mysql:mysql mysql
